How we boosted Stockwell’s NPS score by a whopping 22 points

A teeny tiny project that had a big impact.

Stockwell AI, a start-up based in Oakland, California, created autonomous smart vending machines that offered everyday items. Shoppers could unlock a store via their phone, grab what they needed, and be automatically charged using AI and computer vision for a seamless experience.

About 6 months into my time at Stockwell, the search for our next investment group was underway. It became clear that in order to build a stronger case for acquiring our next round of funding, we’d want to improve our NPS score. At the time, the only way we collected NPS scores was via email—so, we set out to create simple solution to capture an NPS score in our consumer app.
